Why is my Rheem Guardian PowerVent not producing enough hot water?

If your Rheem Water Heater isn't providing enough hot water, try these steps: First, adjust the thermostat to a higher setting. If that doesn't work, inspect and clean the burner orifice and burner plate. Also, check the gas supply pressure and manifold pressure. A partial draw test can help verify the thermostat's functionality. Check the thermistor with ohms resistance test. Inspect and replace the dip tube if necessary. Finally, adjust the peak hour demand.
